Recommendation on a good book on replenishment (DRP) using SAP SCM 5.0

Question

Hi,
Appreciate that anyone can recommend a good, solid book on replenishment planning using SAP APO.
We don't find that SAP's documentation is helpful on replenishment planning of the global supply network, and it dos not seem to have a thoughtful design and well defined process. e.g. transport and shipment scheduling under the gATP documentation, which is clearly designed for sales order taking, and vaguely mentioned that the process can be apply for STR/STO. To me, it does not seem that author fully understand the entire supply chain planning process, from planning to execution in this regard. Another example, SAP documentation says that PP/DS heuristic can plan STR, but when you use it, then you realized that you really can not combine shipments and the planning process and execution are completely falling apart, as the scheduling dates, such like MAD, transport planning dates, pick/pack are not visible in APO nor integrated with planning process.  out of sync with R/3. If using SNP, then we realized that the SNP heuristic is too simple to deal various different supply/demand situations, and have to adopt a completely different set of tools from production planning. 
We have very tightly integrated global supply chain process for manufacturing, replenishment (DRP) and customer service.  APO, having such sophisticated production planning functions, can not even handle such common marine transport planning well.  We have both liquid and solid products with transport mode being marine, rail car, truck, barge etc.  It is being a real challenge to plan our supply chain using APO.
Thank you in advance. Also appreciate anyone can share their experience.

Hi,
Check whether your Instance is up if not bring up the instance first. Try to logon to instance with DDIC user and reset the password to standard i.e 19920706.
Re-try the installation.
