Planning file update upon GR 101Mvt (PP/MM)

Dear All,

We are facing issue with planning file not getting updated upon GR for externally procured parts

These parts are with MRP type PD ,works with scheduling agreements and GR is for inbound delivery's

I know ,there are settings via OMIY which can force planning file update upon any goods movement and my question is why this happens for specific movement like 101 Mvt .

Also ,when testing found its updating planning file mostly for mvt like 311 etc

Let me know ,if there are any possible cause of this issue

thanks,Srini
