Copying of Lines from "Requisition worksheet" to "Planning Worksheet"

Hi,
My Client has only Manufacturing Foundation License. In this regards it is unable to run ‘Regenarative Planning’ in the form of “Planning Worksheet”.

To bypass this I have done all the SKU Configurations necessary. Based on this I am able to to run “Requisition Worksheet” batch job. Then I am ‘copying’ all the lines suggested in the “Requisition Worksheet” and ‘pasting’ this in the “Planning Worksheet”. I am finding all the ‘Accept action messages’ have been checked.

After that I am carrying out the Action messages to generate Production Orders etc.

Is this a valid system to byepass ‘Regenerative Planning’ ? Where problem may occur by this copying and pasting from “Requisition Worksheet” to “Planning Worksheet” ?

Please advise.

Thanks & with regards,
Jaideep Ghosh
