Hello,
We have external material number format, example : X-XXX-XXX-XXX, so any material created should have the said format.
So we used user exit in "conversion exits of matnr: CONVERSION_EXIT_MATN1_INPUT ' to validate material no & throw error message .
These conversion exits are called whenever material is created thru tcode: MM01, changed in MM02.
But when any material created using BAPI / Idoc, these conversion exits are not called.
Please let me know the solution such that material number format is validated when created thru all means.
Thanks,
Sridhar
