integration technical feasibility

Former Member — Wed, 25 Oct 2006 17:31:46 GMT

We are posting the following inquiry in order to verify the technical feasibility of a requirement for a system we are currently specifying.

The situation is the following:

We need to create a Purchase Order (PO) in SAP R/3 from an external application

Instead of entering the transaction and then selecting Purchase Requisitions (PR) or Quotations (Q) to include in the PO, the order is exactly the other way around: having the user selected a series of PRs or Qs, allow him the creation of a PO passing this PR and Q information as parameters.

Our constraint is that we need to emulate the behaviour of ME21 standard transaction without re-writing the logic, and BAPI_PO_CREATE1 does not cover all the functionality that our business requires (in fact, using a BAPI requires developing the front-end logic anyway). BAPIs are not an valid option in this case (at least in the way we know them).

We have learned that the ME21N transaction (enjoy transaction) allows to drag & drop a PR from the Document Viewer “pasting” this information into the PO and carrying out the validations.

The questions therefore are:

1) Is it possible to pass a series of PRs or Qs as parameters to a SAP transaction from an external application? We intend that the shop cart on top of ME21 “understands” the dropping of a document; could it be possible for the transaction to “understand” the same information coming from outside SAP?

2) If possible, how does it work?

3) In case it is not possible, our fallback is to embed SAP WEB GUI screen in our application, but we need to change the Look & Feel. How far can we go? Is it possible to re-design the WEB GUI to make a different presentation of the data (lay-out, colours, grids, etc)?

Regards,

Miguel.

you can create a composite process in nw04s where your external application will pass information to a Guided Procedure defined in SAP GP Design Time (see [original link is broken]) where a callable object of type "SAP Transaction" (see http://help.sap.com/saphelp_nw2004s/helpdata/en/43/f066f5cec64c5de10000000a155369/frameset.htm) will present ME21 prepopulated with data from external system to the user
