I've had several clients recently who've wanted to use ProcessFlow to "Approve" purchase orders. Using Design Studio we removed the "Release" function from PO20 & PO23 and instead added a button to trigger ProcessFlow.
This has worked out very well but (of course) we had a couple of issues to resolve:
In the notice back to the buyer that their PO was approved or not approved we wanted to include the URL back to the PO in question. This required us to "escape" the PO number, release and code string so that the buyer could click the URL link in the email notice.
Using an Assign node, we assigned the following value to the "PO" variable: URLEncoder(PCR_PO_NUMBER+PCR_PO_RELEASE+PCR_PO_CODE) and then we referenced that variable in the URL string: http:///lawson/portal/?_PDL=PROD&_TKN=PO20.1&_HK=0001 (Company 0001 was hard coded).
The 2nd, and more interesting of the issues, was the AGS call to PO22 to perform the Release of the purchase order. The AGS call we originaly designed worked for all of our PO's except for Blanket PO Releases. The sames AGS call that released standard PO's wouldn't work for blanket PO's. We opened a case with Lawson, they duplicated our issue and even wrote up a PT to resolve.
When this got to the developers they came back with a simple, but obscure workaround. We had to reference the PO number, release and code twice (see below) but once we did that, the issue was resolved. Now all PO's release correctly.
AGS call to release PO's via ProcessFlow:
