Capture the Invoice Split Reason and update it in the invoice header text

Question

Hi All,
We have a requirement where we need to capture the invoice split reason and update the reason in the one of the invoice header text.
Problem is the routine where the split criteria is being determined is called a number of times, so how will we determine at what time of time do we need to capture the split reason. I mean at what iteration of the routine will we know that the split value is the right value.
Is there any way to determine the number of iterations of a routine written for split?
Require your valuable inputs for this issue....
TIA

Hi,
Is your invoice split reason maintained in the header or item level?
Try coding your logic in user exit MV45AFZZ and update header text using text id and save it in header text using
FM [SAVE_TEXT|http://help.sap.com/saphelp_40b/helpdata/en/d6/0db8ef494511d182b70000e829fbfe/content.htm].
Before this logic use FM [READ_TEXT|http://help.sap.com/saphelp_nw70/helpdata/en/d6/0db8c8494511d182b70000e829fbfe/content.htm] to determine if the header text is already updated. If yes,exit else save your HEADER_TEXT using SAVE_TEXT.
This code can be written under FORM_USEREXIT_SAVE_DOCUMENT_PREPARE.
