Describe the bug
When trying to run UPDATE query

UPDATE dbo.dpp_dppdocumentdata
SET dpp_documenttype = dpp_documenttype
WHERE  dpp_document = '0611516d-a6a5-4b43-9cb0-c400530ec98a'

SQL4CDS rejects to execute with error

Invalid column name 'dpp_documenttype'.

Even if I am 100% sure column with this name exists (I double checked this by running query:

select * from metadata.attribute 
where entitylogicalname = 'dpp_dppdocumentdata'
and logicalname = 'dpp_documenttype'

and this query returns single column

To Reproduce
I believe this is unique for my setup - I am just looking way of deeper troubleshooting this on my side.

Expected behavior
Properly accepting existing columns for a table

Additional context
I have column with same name (and type - this is Text column) in other Entity / Table - and there similar query works fine
I compared configuration for 2 columns using Metadata Browser tool - I see no differences between columns (1 that works and 1 that does not work) - so to me this looks like mystery
