Procurement using webbased catalogs
we are using the OCI (Open Catalog Interface) for procurement (me51n, me21n) in an ECC 6.0 which works fine with one default catalog. Now we are looking for an solution for connecting several vendor catalogs with the SAP-system. Our options so far are:
1) Setting up a website where you can select different vendor catalogs.
2) Coding an selection screen which is referring to different vendor catalogs stored in customizing.
3) Using a 3rd party application which is not really an option.
Are there any other alternatives or best is there an SAP-standard for this problem?
