I think what @jayasri is looking for is rather simple. (please correct me if I am wrong)
- She wants some drugs to be raised in quotation (that are sold in the pharmacy and those are stocked)
- there are other drugs, she wants Doctors to prescribe, for which there would be no quotation. but patients can buy them from outside.
Simple answer: We don’t have this feature yet. Simplest bit would be to just leave the stock status for such drugs in ERP to be zero. On quotation, they will be shown in red, and the billing person can just remove them from the quotation.
not so simple answer: This can be built. Follow up on “orderable” discussion in this thread
