Required privileges on HANA (SPS 9) to view procedure definition without DATA ADMIN role

Dear all,

We have a customer that uses HANA SPS 9 and we need to create a special account that can read definition of store procedures. We do in this way:

SELECT PROCEDURE_NAME, DEFINITION FROM SYS.PROCEDURES WHERE SCHEMA_NAME='SBODEMOGB' and PROCEDURE_NAME= 'SBO_SP_TRANSACTIONNOTIFICATION'

Unfortunately if we create a new user without the DATA ADMIN role then we always see NULL values in the definition column. Our customer doesn’t allow us to use an account that has DATA ADMIN role.  It looks that maybe “SELECT METADATA” can be used but it was added in SPS 11 so we can’t use it.

Does anybody know what the minimal privilege to access the procedure definition is?

Many thanks in advance
