Assign System Alias to Catalog

To ensure that catalogs are only replicated for specific system aliases, you assign the relevant system alias to the catalog.

Context

A backend system connected to a frontend system usually contains technical catalogs assigned to different software components. The catalogs are replicated to the frontend server for a particular system alias which is usually associated with a software component. For example SAP S/4HANA catalogs associated with Financials are assigned to system alias S4FIN. The IDs of the replicated catalogs have the following syntax: <catalog ID>:<system alias>

Procedure

Perform the following steps on the front-end server:

Start Maintain Table Views (transaction SM30)
In the Table/View field, enter the view /UI2/VC_ALIASCAT.
Enter the relevant system alias for your catalog.

Example

You have two technical catalogs assigned to different software components:

SAP_TC_FIN1
SAP_TC_LO1

To define that catalog SAP_TC_FIN1 is replicated for system alias S4FIN and catalog SAP_TC_LO1 for system alias S4LO, you enter the following entries in the table:

Table 1:
Catalog ID	System Alias
SAP_TC_FIN1	S4FIN
SAP_TC_LO1	S4LO

The replicated catalogs will have the following IDs:

SAP_TC_FIN1:S4FIN
SAP_TC_LO1:S4LO

The mapping of the catalogs to the system aliases avoids duplicates like the following:

SAP_TC_FIN1:S4FIN
SAP_TC_FIN1:S4LO
SAP_TC_LO1:S4FIN
SAP_TC_LO1:S4LO
