Shopping cart changes during the approval limit

[former_member692171]

The requester creates a shopping cart with one item:

Item: pins

amount: 5

price: 1€

The approver can reduce or increase the amount of the pins.

But the amount of the pins should only be reduced!

How can I achieve this?

environment: SRM 7.01

workflow: process controlled workflow

Hi David,

You will have to compare the number of pins from the FM that Ritesh pointed out which is BBP_PD_SC_GETDETAIL and that of the buffer and see if it has changed then raise a message. All this has to be done in the DOC_CHECK_BADI.

The buffer can be arrived at using the factory class/sapsrm/cl_pdo_model_factory 's Get_instance method and inturn the get_detail method.

Hi all,

many thanks for the quick responses.

I implemented the "DOC_CHECK_BADI" Badi.

In Badi method I call the function module "BBP_PD_SC_GETDETAIL" and the Method "get_detail" of the class "class/sapsrm/cl_pdo_model_factory".

I get the return parameters "item_tab (table, BBP_PD_GETDETAIL FM)",es_headerand et_item (get_detail Method).

I can not find the buffer for the old value (amount). --> only the current value.

In other export parameters (fm, and the class) I could not find a old value (field "amount").

Where are the old values (prior to the change of approver) are stored?

With Regards,

David

Hi David,

In the check badi the iv_doc_guid that you get is the changed version guid of the header when you pass this guid to bbp_pd_sc_getdetail you get changed version of the actual data.

Now to get the old data, in the bbp_pd_sc_getdetail- ES_HEADER structure there is a field called ACTIVE_HEADER which holds the active version of the guid. If you pass this to bbp_pd_sc_Getdetail again you will get the old data and hence you can compare.

Hope it fixes your issue. -)

Hi Naveen,

thanks for your help 🙂

In the function module "bbp_pd_sc_getdetail" does not exist the parameter "es_header",only the "e_header" return parameter.

- e_header type BBP_PDS_SC_HEADER_D

In BBP_PDS_SC_HEADER_D i can't find the field "active_header".

The GET_DETAIL method (class /SAPSRM/CL_PDO_MODEL_FACTORY) has the return parameter "es_header" with the field "active_Header".

The value is only a amount of 0.

Where is the mistake?

Hi,

Sorry for the late reply.

If you place the breakpoint in the change badi then you will notice the above solution that I gave works. As the buffer is not updated.

But when you place a breakpoint in the check badi then the above doesnt work , since the buffer is already updated.

I cant think of anyother solution apart from the two that  I list below

1. Create another zfield of boolean type in the item structure.

Set this  field in the change badi based on the below logic

it_item of change badi will have the new value for the field.

BBP_PD_SC_GETDETAIL-et_item will have the old value.

check the difference and set the zfield .

Now in the check badi see the value of the zfield and based on that show the message

2. Use import- export parameters. ( I dont like this solution )

Hope this helps.

Hi David,

Are you only looking to flag the error whenever Approver change the Price i.e. increase then the original one? If so then you could utilize DOC_CHECK_BADI with FM BBP_PD_SC_GETDETAIL where you can get details of shopping cart with GUID or SC number and validate it accordingly.

Hope this helps.

Thank you

Hi,

BADI "bbp_doc_change_badi " triggers during sc approval.

You can put a check in the BADI with shopping cart status in "awaiting approval".
