Extracting data from Cluster tables STXH & STXL

Hi All.

I have got a requirement where we are getting rid of our SAP system & moving to another system, but will be keeping our the SQL database. SQL queries will be used to retrive any historical data initally maintained on SAP.

The SAP scenario we use is around Service Tickets.

The requirement I have is based around the Notes held against a Service Tickets & would like to know if there is any way of extracting the notes (Field: CUSTD, Table: STXL & STXH) so that we can view at a later stage via a SQL query. At the moment we use the READ_TEXT function but once SAP has been de-commissioned we will lose this function.

Has anyone come across a scenario like this earlier on & if so can you advice me what were the steps that were taken bearing in mind that the solution provided needs to work once we have got rid of the SAP system.

Thanks.
