Create Calculation view using following details -Pls help me out in creating SQL in SAP HANA ?

Steps to get the REGION data in CRM

1. 1. Get the Object ID ( OBJID )from HRP1000 by passing Sale Org (L001,L002…) to field MC_SHORT, PLVAR = 01, OTYPE = “O”, ENDDA = “31.12.9999”
2. 2. Get SOBID from HRP1001 by passing OBJID from step1 & PLVAR = 01, OTYPE = “O”, ENDDA = “31.12.9999”, RSIGN = “A” – This will give you the 1^st higher level
3. 3. You can get the description (MC_STEXT) of 1^st higher level from HRP1000 by passing OBJID = SOBID from step 2, PLVAR = 01, OTYPE = “O”, ENDDA = “31.12.9999”
4. 4. Keep doing the 2^nd step by passing the SOBID from step2 to OBJID to HRP1001 and PLVAR = 01, OTYPE = “O”, ENDDA = “31.12.9999”, RSIGN = “A” to get next higher level and do the Step 3 to get the description
5. 5. You need keep doing the step 2 and 3 till you don’t get any row from step 2
