1.3.2. logically separate and independent from SAP BI

1.3.3. Application Component BW-BCT-ISR-PIPE (PIPE only)

2. POS Analytics

2.1. based on BI

2.1.1. deployed as part of BI_CONT

2.2. default views on transaction data

2.2.1. by Article/Store

2.2.2. by Receipt/Article

2.2.3. Store Performance

2.2.4. Cashier Performance

2.3. role-based reporting

2.3.1. default roles:

2.4. uses BI InfoObjects for data storage

3. PIPE

3.1. stands for POS Inbound Processing Engine

3.2. storage

3.2.1. /POSDW/TLOGS - TLog information

3.2.2. /POSDW/TLOGL - TLog information for very large TLogs to improve storage efficiency

3.2.2.1. rarely used

3.2.3. only header fields are visible using SE16

3.2.3.1. line items and supplemental data stored as binary strings in LRAW fields not visible in SE16

3.2.3.2. can be accessed using function modules
