Error while reading data of infoprovider Z_MSI$N

Hi,

While we execute the BEx query built on Z_MSI DSO, we get following errors:

We are running SAP BW on hana DB, SP 09. We have archieved data into SYbase IQ for period <= 2012. While we execute BW Report, we give current date periods which data is physically present in Hana db, we face above errors. Couldn't understand why the above error comes even for fetching data from hana db. Connection to SYbase IQ are fine.

Also, error seems to be peculiar where it shows errors some time and at later point the same executes. This is continuing like a loop.

Couldn't understand such a behaviour of BEx report execution all of the sudden. Same case happens with many sales reports.

Kindly help me to resolve this.

Regards,

Antony Jerald.
