2 possible solutions:
  • Synchronize the catalog cache by executing program /UI2/CHIP_SYNCHRONIZE_CACHE.
  • See SAP Note 1759544 Information published on SAP site: Erroneous UI2 CHIP not shown in catalog. This is applicable if your SAP NetWeaver release is below SP06.
3 Verify if the CHIP is created.
  1. Call the Page Builder Configuration Service and check whether the CHIP is found in the default catalog /UI2/CATALOG_ALL. The URL format is: http://<host>:<port>/sap/opu/odata/UI2/PAGE_BUILDER_CONF?sap-language=EN&sap-ds-debug=true
  2. Choose the collection Catalogs.
  3. Choose the collection Catalogs('%2FUI2%2FCATALOG_ALL')/Chips - /UI2/ is escaped.
  4. Search for your CHIP.
  • If you find the CHIP here but it does not exist in your catalog then refer to reason 5: CHIP parameters do not exist in the catalog cache.
  • If you did not find the CHIP, refer to reason 5: CHIP does not exist in default /UI2/CATALOG_ALL or in the catalog cache.

    2. If the CHIP exists in the table, check its parameters in the catalog cache. See reason 5: CHIP parameters do not exist in the catalog cache.
5 CHIP parameters do not exist in the catalog cache.   Look up the CHIP ID (GUID) in the table /UI2/CHIP_CPARA. Contact the administrator if you cannot find any CHIP parameters.
