Transformation from datasource to DSO inactive in BI

Hi Experts,

Some changes has been made on the Z table-ZACCOUNTCLASS on ECC sie. We have our master data extrctor over this table. after the change datasource is not been replicated in BI, still if i click on the datasource it is showing last changed on of today and transformation over it are inactive and all other datasources using this object also have transformations inactive. Does changes on ECC side impacts the datasouces in BI without replication?Pls suggest.

Thanks and Regards,
