Auto Release invoice block：指当我们一开始做INVOICE的时候，是BLOCK，但到某一点之后，条件成熟了，已经不能再BLOCK了，这种情况就可以直接用MRBR的AUTO RELEASE去操作

大意指

如PURCHASE ORDER QTY = 100PC

一开始收货了60PC，但是发票却做了20PC，按说这时候产生的INVOICE是BLOCK

但到后来又做了一张CREDIT MEMO 20PC，即80 – 20 – 60， 此时的INVOICE就不能再BLOCK了，因此你可以用这个MRAR的AUTO RELEASE去清除这个 BLOCK

演示1 – GR BASED IV

1. Create Purchase Order

TCODE: ME21N

PO QTY = 100PC

PO PRICE = 1 EUR

2. Goods Receipt

TCODE: MIGO

GR QTY = 50 PC

3. Invoice

TCODE: MIRO

Invoice Qty = 60 pc

Display Invoice

会发现此INVOICE已经BLOCK了，并且是因为QTY原因。

4. Goods Receipt again

TCODE: MIGO

再次收货 10PC

以我们的理论，应该是50 + 10 = 60 PC，刚好与INVOICE的60相同，这样的话，刚才产生的INVOICE不就刚好相同了，可以AUTO RELEASE BLOCK 了？

5. Auto Release Block

TCODE: MRBR

结果显示以下

表示没结果。为什么呢？这是为什么呢？

别急，再看看 演示2

演示2 – GR BASED IV

1. Create Purchase Order

TCODE: ME21N

PO QTY = 100PC

PO PRICE = 1EUR

2. Goods Receipt

TCODE: MIGO

GR QTY = 50 PC

注意：此时记下所产生的MATERIAL DOCUMENT: 5000011634

3. Invoice

TCODE: MIRO

INVOICE QTY = 60 PC

INVOICE AMOUNT = 60 EUR

Display Invoice

仍然是BLOCK

4. Goods Receipt Again

TCODE: MIGO

看清楚操作，很重要啊，很重要。

是用SUBSEQUENT DELIVERY + MATERIAL DOCUMENT 来处理的。

这个MATERIAL DOCUMENT是一开始收货所产生的。

5. Auto Release Block

TCODE: MRBR

成功 AUTO RELEASE

演示3 – GR NOT BASED IV

1. Create Purchase Order

TCODE: ME21N

PO QTY = 100PC

PO PRICE = 1EUR

NO SELECT GR BASED IV

2. Goods Receipt

TCODE: MIGO

GR QTY = 50

3. Invoice

TCODE: MIRO

INVOICE QTY = 60 PC

INVOICE AMOUT = 60 EUR

Display invoice

4. Goods Receipt Again

TCODE:MIGO

GR QTY = 10PC

5. Auto Release Block

TCODE: MRBR

总结

针对GR BASED IV，如果是第二次收货，一定要用SUBSEQUENCE DELIVERY 或者用CREDIT MEMO去扣减INVOICE的数（此选择没有演示）

如果是GR NO BASED IV，则可以直接用正常的GR + PO NUMBER去收货即可。

这样设计的原因是因为GR BASED IV的原理

A goods receipt and then an invoice with quantity variance was posted to a purchase order with goods-receipt-based invoice verification.After another goods receipt, the quantity delivered is greater than or equal to the calculated quantity.In spite of that, the invoice is not released automatically. Why?

The second goods receipt was presumably not posted with regard to the first one (material document).As the invoice refers to the first goods receipt, the system does not take the second goods receipt into account during the release.

As of Release 4.6B, you can post the second goods receipt with regard to the first goods receipt.For this, the second goods receipt must be posted as ‘subsequent delivery’ in Transaction MIGO.
