We have a requriement for sales order credit memo.
1)Our customer is asking us to create a custom button in additional data 1 tab(VA01).Once the user clicks on the button, workflow should get triggered.Because once the workflow is triggered they want to generate the unique number every time the workflow is triggered and this number should be tailored in the header text of VA02.
2)Once the WF is triggered from the VA01 then the user may do some changes in VA02 tcode for already triggered workflow
(with same sale order number) which is in progress.So this will be a problem again.Customer is asking to disable some fields like sold to, ship to, sale order reason code and in item level (material , quantity, and condition value) until the previous workflow is approve/rejected.A warning message should be displayed like 'Workflow approval is in progress'.
So is this solution feasible?..if possible please share me your ideas.
