Integration of new ECI Userexits
Integration of new ECI UserexitsSpecific links to CAX systems may require the implementation of specific userexits. For an easy usage via ECI it is then necessary to call them with the standard ECI functionality.
 |
Using the ECI function eci_lgv_run you may already call decision tables which call userexits within Agile e6. Additional ECI function, which supports userexit calls: eci_usx_cal, eci_sel_usx, eci_nos_usx, eci_sel_men, eci_nos_men. |
Here an example of how a customer specific ECI function (ecc_test_usx) is integrated via a shared library.
The ECI function ecc_test_usx issues a message in the Agile e6 window. This ECI function is announced to the EDC administrator with the function EciEcc_Entry by calling edb_add_function.
