ATP: Its Not For Everybody
Some industries dont think they need ATP
Consumer Products companies sometimes wait until the delivery
and rely on their forecast.
If you know the products not going to be available when theATP check is done, but it will by the time you need to ship it.
If everything you sell is make-to-order
Hint: You can trigger production from a sales order with APOs
gATP
If you tried it for a while, but i t could never find the product you
.
Hint: This sounds like a consult ing issue (consultant issue?).

What Will it do for Me?
Prevent over-commitment
Manage backorders
Let you search in multiple locations (gATP)
Automate a manual process
Reduce the amount of time it takes to process an order
Give you visibil ity of your sales commitments for every materialyou ATP check, regardless of the results.
Give Production something besides a forecast to work with.
Allow you to prioritize customers and realign commitments ofconstrained product when necessary.

What Should it NOT Do!
Render results that are impossible to understand.
Return results you know are incorrect.
Confuse rather than help.
Annoy rather than delight.
Increase shipping costs.
Decrease fil l rates.
Lower customer satisfaction.
Increase the rocessin time of customer service.
Result in turnover and career changes.

What Happens When an ATP Check is Performed?
The Choices:
A basic ATP check (in APO)
A rules-based ATP check
Product substitution
Location substitution
May include a Calculation Prof ile
A Multi-level ATP check Perhaps in combination with rules-based ATP
A Product Allocation Check
A Production capacity check (Capable-to-Promise)
A combination of the above
