After setting Row Security, the Bank Account Details have dissapeared

We are separating 1 company 00300, for this we have created Inclusive Row Security based on MCU for all the MCU in company 00300. We have created a new Role with sequence id as 9999999, added row security to it and added to our existing user id.

After setting row security, the Bank Applications and table F0030 and P0030G are showing blank values.

We have added 300001 BU to be included in Row security, but when checking in P0030G, Bank account 300001.10129.999 is not appearing. Also the suppliers which have BU as 300001, their bank account details also are not appearing in F0030
