How to call a BAPI that takes a table parameter

[Former Member]

Hi,

I have a BAPI ZHRECMFM_002_PERFRAT_WARNING that has two table parameter one is PERNR_LIST of type HROBJECT and another one is PERNR_PERFRAT of type ZHRECMGLS_002_PERNR_PERFRAT that consists of two elements pernr and perf_text.

I need to set PERNR_LIST(set of pernrs) in my WDA and call the BAPI.that BAPI will return PERNR_PERFRAT table parameter.

1.How will I pass PERNR_LIST(that consists of multiple HROBJECTS) to the BAPI.

2.After executing the BAPI How will I iterate thru PERNR_PERFRAT to get pernr and corresponding perf_text.

I tried to set PERNR_LIST using the following way suggested SivaRama Krushna

IPrivate<viewname>.I<nodeame>Node prNode = wdContext.node<node>();

IPrivate<viewname>.I<nodeame>Element prEle;

for (int i = 0; i < table.size(); i++) {

HROBJECT pernrList = new HROBJECT();

pernrList.setPernr(pernr); // Set the pernr from current record

prEle = prNode.create<nodeame>Element(pernrList);

prNode.addElement(prEle);

}

My code

IPrivateVEcmPlanningView.IPERFWARNNode prNode = wdContext.nodePERFWARN();

IPrivateVEcmPlanningView.IPERFWARNElement prEle ;

Hrobject pernrList = new Hrobject();

pernrList.setPlvar("01");

pernrList.setOtype("NA");

pernrList.setObjid(pernr);

prEle= prNode.createPERFWARNElement(pernrList);

prNode.addElement(prEle);

Type Mismarch:cannot convert IWDNodeElement to IPrivate<viewname>.I<nodeame>Element.

Please help me in resolving this issue

Thanks

Hi Bala,

You did not provide the node(table) name that you created for PERNR_LIST. Try this out in your Planning VAC of MSS ECM DC:

// you need to create reference to the PERNR_LIST node 
// I am assuming the node name is PERNR_LIST
IPrivateVEcmPlanningView.IPERNR_LISTNode prNode = wdContext.nodePERNR_LIST();
// you need to create element of the type PERNR_LIST node 
IPrivateVEcmPlanningView.IPERNR_LISTElement prEle ;
Hrobject pernrList = new Hrobject();
pernrList.setPlvar("01");
pernrList.setOtype("NA");
pernrList.setObjid(pernr);
prEle= prNode.createPERNR_LISTElement(pernrList);
prNode.addElement(prEle);

Siva

Thanks for the code.it is not giving any syntax errors but unfortunately i cannot write this logic in view.I have to write this in component controller.

Please let me know how i can write this

I figured out how to write.

I will come back if i have any issues

Hi,

I wrote the following code

float amount = 0;

Zhrecmfm_002_Perfrat_Warning_Input input = new Zhrecmfm_002_Perfrat_Warning_Input();

wdContext.nodePERFWARN().bind(input);

if(cpamt!=null)

{

String amt = "";

amt = cpamt.toString();

amount = Float.parseFloat(amt);

}

//wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("Amount"+amount);

if(amount>0.0){

pernrCounter = 1;

IPublicVEcmPlanningComp.IPernr_ListNode prNode = wdContext.nodePernr_List();

IPublicVEcmPlanningComp.IPernr_ListElement prEle ;

Hrobject pernrList = new Hrobject();

pernrList.setPlvar("01");

pernrList.setOtype("NA");

pernrList.setObjid(pernr);

if(prNode!=null)

{prEle= prNode.createPernr_ListElement(pernrList);

prNode.addElement(prEle);

//wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("Inside Amount"+prNode.size());

}

and context is like this

PERFWARN 0:n

output 0:1

Pernr_List 0:n

Perf_rat 0:n

it is not giving any syntax errors but when i am executing it si giving runtime erros saying that

com.sap.tc.webdynpro.progmodel.context.ContextException: Node(VEcmPlanningComp.PERFWARN.Output.Pernr_List): cannot bind or add elements because the node has no valid parent

* at com.sap.tc.webdynpro.progmodel.context.Node.prepareAddElement(Node.java:656)*

* at com.sap.tc.webdynpro.progmodel.context.Node.addElement(Node.java:635)*

Please let me know how to resolve this

Hi Bala,

Your context structure is:

PERFWARN 0:n

output 0:1

Pernr_List 0:n

Perf_rat 0:n

I think this is not exact replica of model. i.e. you have not bound entire model to Controller.

General BAPI or RFC model is like this:

<BAPI>Input

-Input tables

-Output

--Output tables

Input tables are used to send data and output tables are used to retrieve data.

In your case, the model may be like this

Zhrecmfm_002_Perfrat_Warning_Input

-Pernr_List

-Perf_rat

-Output

-

---

Pernr_List

-

---

Perf_rat

-

---

<Return>

-<Return>

The Component controller must contain all these model node.

Your problem is com.sap.tc.webdynpro.progmodel.context.ContextException: Node(VEcmPlanningComp.PERFWARN.Output.Pernr_List): cannot bind or add elements because the node has no valid parent

You are trying to send data through output table, that is why you are getting exception. Use input tables for sending data and output tables for see the result or any other manipulataion.

Hi Bala,

Try following:

float amount = 0;
Zhrecmfm_002_Perfrat_Warning_Input input = new Zhrecmfm_002_Perfrat_Warning_Input();
wdContext.nodePERFWARN().bind(input);
if(cpamt!=null)
{
String amt = "";
amt = cpamt.toString();
amount = Float.parseFloat(amt);
}

if(amount>0.0){
pernrCounter = 1;
Hrobject pernrList = new Hrobject();
pernrList.setPlvar("01");
pernrList.setOtype("NA");
pernrList.setObjid(pernr);
input.addPERNR_LIST(pernrList);

}

I need to add multiple HROBJECT not just one so i think

float amount = 0;

Zhrecmfm_002_Perfrat_Warning_Input input = new Zhrecmfm_002_Perfrat_Warning_Input();

wdContext.nodePERFWARN().bind(input);

if(cpamt!=null)

{

String amt = "";

amt = cpamt.toString();

amount = Float.parseFloat(amt);

}

if(amount>0.0){

pernrCounter = 1;

Hrobject pernrList = new Hrobject();

pernrList.setPlvar("01");

pernrList.setOtype("NA");

pernrList.setObjid(pernr);

input.addPERNR_LIST(pernrList);

}

wont work

Hi Bala,

What I had given was a sample code from which you can take the clue. To send table parameter as input you multiple times use add method.

It is up to you what logic you are using to send table parameter. Once again I am giving you the sample code. Try to take clue from it:

//Initializing The RFC model class
Zhrecmfm_002_Perfrat_Warning_Input input = new Zhrecmfm_002_Perfrat_Warning_Input();
wdContext.nodePERFWARN().bind(input);

//Sending 2 rows to table parameter to RFC input
Hrobject pernrList = new Hrobject();
pernrList.setPlvar("01");
pernrList.setOtype("NA");
pernrList.setObjid(pernr);
input.addPERNR_LIST(pernrList);

Hrobject pernrList1 = new Hrobject();
pernrList1.setPlvar("02");
pernrList1.setOtype("NA");
pernrList1.setObjid(pernr1);
input.addPERNR_LIST(pernrList1);

OR

//Using some kind of for loop. Sending 5 rows to table parameter to RFC //input
for(int i=0;i<5;i++){
          Hrobject pernrList = new Hrobject();
          pernrList.setPlvar(""+i);
          pernrList.setOtype("NA");
          pernrList.setObjid(pernr);
          input.addPERNR_LIST(pernrList);
}

//Executing the RFC
input.execute();

OR

//if RFC execution is done from some different method
wdContext.nodePERFWARN().currentPERFWARNElement().modelObject().execute();

Hope you got some insight as to how table parameter have to be sent as input to RFC.

Warm Regards,

Gopal

hi,

a little off topic here, but i have an SAP note that wants me to make some changes to VEcmPlanningComp but I dont know where or what tool to use to make the code changes? Can anyone help.

note is 1288670

thanks

Hi Bala,

In your code

prEle= prNode.createPERFWARNElement(pernrList);
prNode.addElement(prEle);

Can you please try like this?

prEle= wdContext.createPERFWARNElement(pernrList);
prNode.addElement(prEle);

I will explain the difference

If you want get the reference of the node element that already exist then we use this coding

//prEle= prNode.getPERFWARNElementAt(i);

now in prEle you have (i+1) record of PERNR_LIST.

Hope you understand.

I tried with the above suggestion.

then also it is giving syntax error saying that

the method createPERFWARNElement(zhrecmfm_002_Perfrat_warning_input) in the type IPrivateVEcmPlanningView.IContextNode is not applicable for the arguments(Hrobject)

[Former Member]

HI Bala,

I am not sure of the node structure but here is an example for you

Parent Node :- ParentNode

tables:- table1,table2

table 1 and table2 are the other two node which ar eof type table

you can try this

Parent p=new parent().

table1 t1= new table1(p); //if required pass p

t1.set<>;

....

table2 t2=new table2(p);

t2.set<>.....

p.settable1(t1);

p.settable2(t2);

wdContext.nodeParent.bind(p);

regards
