I am working on SRM 7.0 and utilizing process controlled workflow to model my approval workflow scenario. Below are the steps that i have done but still i have not got the desired result. May be i am missing something which the forum members can let me know.
step 1: i have copied the standard function module /SAPSRM/WF_BRF_0EXP001 and made chnages in the code based on the logic to populate the ev_value.
basically in the coding it is done this way.
EV_TYPE = 'B'.
EV_LENGTH = 1.
EV_OUTPUT_LENGTH = 1.
EV_DECIMALS = 0.
EV_VALUE = ABAP_FALSE. " no processing
EV_DATA_MISSING = 'X'.
get event object
LO_WF_BRF_EVENT ?= IO_EVENT.
get Context Container from BRF event
LO_CONTEXT_PROVIDER = LO_WF_BRF_EVENT->GET_CONTEXT_PROVIDER( ).
CALL METHOD LO_CONTEXT_PROVIDER->GET_DOCUMENT
EV_DOCUMENT_GUID = LV_DOCUMENT_GUID
EV_DOCUMENT_TYPE = LV_DOCUMENT_TYPE.
Get shopping cart instance
LO_WF_PDO_SC ?= /SAPSRM/CL_WF_PDO_IMPL_FACTORY=>GET_INSTANCE(
IV_DOCUMENT_GUID = LV_DOCUMENT_GUID
IV_DOCUMENT_TYPE = LV_DOCUMENT_TYPE
IV_PDO_EVENT_HANDLING = ABAP_FALSE
custom logic with the GUID of the shopping cart then populate value accordingly
EV_VALUE = ABAP_TRUE.
step 2: create an event ZEV_001 linked to expresion ZEX_001.
step 3: expression ZEX_001 is of type 0FB001. and the xpression is as below.
ZEX_002 = OB_WF_TRUE.
step 4: ZEX_002 is of type 0CF001 and output result type is B. the attached function module is the one created above by copying /SAPSRM/WF_BRF_0EXP001
no parameters provided .
step 5: the process step level config completed.
now when i am creating shopping cart go for approval preview its gives an exception occured error . i cant see any dump in the system. however if in the custom fucnction module code if i do not clear the EV_DATA_MISSING. then i d o not get the error but my steps is not executed. Inslg1 log i see the process level executed but return as space.
as per other post in the forum we have to clear EV_DATA_MISSING but that casuing exception eror for me. in the dlg1 log howere the steps expressin i can see executed with return =X.
hope i am made myself clear . feel free to ask for any more info.
i have below question.
1) do we need to copy /SAPSRM/WF_BRF_0EXP001 or /SAPSRM/WF_BRF_0EXP000 for creating a custom FM expression.
2)what does the check box "Calculation of Parameter in Function Module/Badi/method" does
3) how can i do debugging for such FM expression , probably saving the cart and then debugging the expression.
Thanks in advance for any help provided.
