Procedure for System Administrators

Enterprise Search as a Service (ESaaS) currently can consume result item
properties if and only if their first 30 characters are unique.
Example:
Property 1: purchaseOrderItemMainCategoryPartOne
Property 2: purchaseOrderItemMainCategoryPartTwo
As both properties start with 'purchaseOrderItemMainCategoryP', the
response item currently cannot get parsed.
This is a known limitation, as many data bases like SAP HANA support up
to 128 characters for table fields.
SAP DDIC supports field lengths up to 32 chanracters only.
