Update field of LIKP through trx VL10X and VL01N/O
I have this problem:
The client ask me change a field of LIKP table, Shipment blocking reason (TRSPG) having in mind that Route Schedule (AULWE) be empty.
This changes must be do it when the user access to anyone of these trxs:
anyway the last four trxs finally go to the first trx that I mentioned (when I do Goto --> Header). My problem is that in save's moment I couldn't find anything (BADI, BAPI, Userexit, etc) that let me verify the field Route Schedule and change the field Shipment blocking reason.
Could you please give me a solution or an idea of what's happing or how I can do this?
I tried some program exits but anyone are active or are called when the user want to save.
In advance...thank you for your help!!
