SAP datasphere task chain: sql procedure not visible

[#1]

I've created an SQL procedure in my Open SQL Schema of SPACE  "SAP_ADMIN.

I'd like to run this procedure in a Task Chain in SAP DSP, in the SPACE_ID = SAP_ADMIN. I'm following this: Run Open SQL Procedures in a Task Chain | SAP Help Portal 

However, even after assigning the privileges to the space as described here: Allow the Space to Access the Open SQL Schema | SAP Help Portal , I'm not able to see the SQL procedure in during Task Chain modelling.

The error showed is: No procedures have been created or the EXECUTE privilege has not been granted to the Open SQL schema. 

Could you please investigate?

• "NCHAR", "STRING", "NVARCHAR", "ALPHANUM", "SHORTTEXT", "INT", "TINYINT", "BIGINT", "CHAR", "DECIMAL", "SMALLDECIMAL", "INTEGER", "SMALLINT", "REAL", "DOUBLE", "FLOAT", "VARCHAR", "BOOLEAN", "DATE", "TIME", "SECONDDATE", "TIMESTAMP"
