| # Types of ATP and CTP checks ERP Enterprise offers a set of order-promising techniques that ranges from standard item ATP to advanced CTP techniques. Standard ATP check An item master plan contains available-to-promise (ATP) information. ATP represents the balance of planned supply and actual demand. You can use ATP information to determine how much you can still sell to customers. Extended CTP checks Component CTP and capacity CTP are extensions of standard ATP, and are used to determine how many items you can produce in addition to the existing production planning. Family CTP For planning on longer term, working with detailed ATP and CTP information is not always useful. ERP Enterprise offers the option of redirecting ATP checks and extended CTP checks to a higher product-family level. Channel ATP checks are always carried out at the level of the item itself. Channel ATP If you maintain channel master plans, you can constrain the allowed volume that is delivered to each channel. ERP Enterprise uses channel ATP to determine how much can still be sold in a particular channel.
