1) just wanted to find what role is played by SAP BI guys in SAP APO.
2 ) Is it necessary for a BI guy to learn the functional part of APO - DP/SNP/DS/PP/gATP etc ?
3) Is there any thing like technical skill set only for SAP APO ?
4)I keep hearing APO has BI built in, then what role does the actual SAP BI guy play.
