Problem with Binding tables to context nodes

[Former Member]

Hi All,

I have a problem with binding tables to context nodes.

I'm using an RFC (FM1) that returns tables with GUIDs. I have to feed these tables as input to a different function module (FM2) for execution.

I tried to bind the tables returned from FM1 to FM2. I've used an input structure of the node, have add the tables to it. I've bound this input structure to the FM2 node.

When I execute the FM2 these table rows are appended to the existing FM2 tables. I actually need just the values to be copied to the input tables.

FM1- ZABC

Node ZABC - OUTPUT - A,B tables (sub nodes)

FM2 - ZXYZ

Node ZXYZ INPUT - X, Y tables (sub nodes)

Structures X1, Y1 of type X and Y respectively

Structure ZXYZ1 of type ZXYZ

Copied values from Output of ZABC A and B into X1 and Y1.

ZXYZ1.addX1

ZXYZ1.addY1

nodeXYZ.bind(ZXYZ1)

Executed FM ZXYZ

Thank you,

Hi Vasu,

It seems you get the results but the older data is still there & you need to clear that data.

You can invalidate the context like wdContext.nodeOutput().invalidate() (you can call this code at time of execute statement)

Hi,,

you need to make loop with you first node size and get the values from first node, and set the values to second node.

you need to create the elements for both the nodes and get and set the values based on the condition, by using the loop you can get the value of every field.

like wdContext.node<nodename>.get<nodename>Elementat(i). - to get the record at " ith " position.

wdContext.node<nodename>.get<nodename>Elementat(i).get<attributename>(); to get the value of a field at a specific position from a record.

after getting the values from the first node you can set that to second node right

may be it can help you,

Cheers,

I've declared abstract lists of type (FM tables). I've added rows to this lists and set this lists to the function module nodes. This way, news rows are not added and the problem is resolved.

In the example I mentioned.

FM2 - ZXYZ

Node ZXYZ INPUT - X, Y tables (sub nodes)

Abstractlist of type input tables (X,Y) in the model

ZXYZ.setAbstractlistX

ZXYZ.setAbstractlistY

Executed FM ZXYZ

Thank you,

Hi

You can use the methods WDCopyService

Example : WDCopyService.copyElements(source, target)

Satish: Is there any other function for copying selected rows of the tables rather than copying the whole node(table). I need some selected rows of first node (table) based on a condition to be copied to the second node.

Nitin: Output node is already invalidated. Even then the rows are appended instead of copy.

Thank you,

Vasu

Hi

Something like your requirement is not there You can check with this method and find some workaround

WDCopyService.copyCorresponding(source, target)

Note :Its parameter is Object type not IWD type

Since u have the object now u can write the retrieving logic based on this.

But I would suggest to get value by getter setter way and hold it in some temporary node.

HI

May be you can fetch the data from the table with looping the table size and catching the

index of the elements . To be more clear .

1 . get the size of the table .

int leadSelection= wdcontext.node<TableName>.getLeadSelection();

for (int i=0 ;i<n;i++)

{

if(wdcontext.node<tablename>.isMultiselected(leadSelection))

{

String name = wdcontext.node<tablename>.getelementatindex(leadSelection).getname();

similarly fetch the size of the other elements from the table .

and set to other RFC as

ZClass abc = new ZClass();

abc.setName(name);

wdcontext.node<NameName>.bind(abc);

and othere thing is when you use Abstract class you can insert only one element at a time .

or may be you may want to set the values direclty to the RFC

AbstractList lst = new ZClass.ZClassList();

ZClass cls = new ZClass();

clas.setName(name)

lst.add(class);

wdcontext.currentRFcNameElement.modelObject.setName(lst);

and

execute the RFC .
