Planning file entry creation via MDAB

Dear all,

I have created a variant in MDAB for a specific plant as I thought I can schedule a job on daily basis. I was under the impression that the Planning File entries for the materials will get created after we run the program in MDAB. After the program run is finished, I could not see any Planning file entry in MD21. Am I missing out any step? The user will run MDBT with his variant having processing key NETCH. Through MDAB, is it not possible to create a Planning file entry for MRP run (MD01/ MDBT) having processing key as NETCH. Please advice. Thanks.
