IDOC conversion rule : Help required for Special conversion routine
I need help regarding SAP IDOC conversion rule. We have a conversion rule for the Instruction Key (DTAWS) field set for CREMAS IDOC to convert value of this field to value "20". We have created this rule in BD79 for the field DATSW. Now we want this rule to be exempted for specific vendor code.
Like for e.g. LIFNR = '23423423' then rule should not be applied or DATWS field should not converted to value "20".
For this we can write special conversion routine and assign it in BD79.
Can anybody help me for handling this scenario in special conversion routine and explain how the above scenario can be handled?
Please help .
yes with option Copy Sender Field....
In the conversion routine function modules you have the interface input and output where you receive and send the values.
