Master Data Maintaince Issue

Hi All

We are trying to maintain master data for Entity Dimension but it says "ID is mandatory" even after entering vaule for ID. The Description field is not visible in the same dimension. As Entity Dimension is the driver dimension for BPF, Work Status hence we do not want to delete the Dimenison. This was all working good till yesterday but accidentily all the master data got deleted and we maintained all the master data except entity as it is throwing error. Please see the below screen shot for more details:

Thanks
