Maximum length of ID??

Hi All,

We are on SAP BPC 10.1 classic and SAP BW 7.4 on HANA.

As per the SAP help portal document,the maximum length of id is 20 characters. In BPC admin web page, i can able to enter account id's more than 20 characters.

Is there no limit of account id's on HANA optimized BPC cubes??

Thanks,

Naidu
