Attempt to generate and install a CA Gen RI trigger and it fails at compile time with a RC=8 and compile error of:
IGYDS1159-E   A "PICTURE" CLAUSE WAS NOT FOUND FOR ELEMENTARY ITEM "XXXXXXX". 

Release : 8.5 and 8.6
Component : CA Gen Host Encyclopedia

The error IGYDS1159-E, is typically caused by an Entity View (within a Procedure Step or Action Block) that has been defined without any attributes included.    Another possibility would be that the Entity Implementation including the Table, Indexes and Foreign Keys may have been incorrectly implemented.   A model consistency check would be suggested to determine the cause of the implementation error, should this be the problem. 

Note - Along with RI Triggers, this error can occur when attempting to compile a module containing a PStep or Action Block that uses the entity that does not contain attributes.
