Troubleshooting: Why are the options Always Post To G/L and Always Post To Stock not available (shown in grey)?

Question: Why some of the options like Always Post to G/L, Always Post To Stock, Can Edit Unit Price, are not available?

Version: 1.8 / 1.9 / 2.0

Possible Reason:

User has enabled “Use setting in User Access Rights” for those settings in System Option Policy. And the user does not have access rights to the above mentioned actions.

Solution:

If you wish to change it back to following setting in Options,

1) Go to Tools> System Option Policy.

2) Change from “Use setting in User Access Rights” to “Use setting in Options”.

Remarks:
Invoicing: These invoicing controls could be applied either:
(a) according to the settings in Tools > Options: - which all users will share the same setting, OR
(b) according to the settings in General Maintenance > User Maintenance > Access Rights - which means different users can have their own setting.
Means, you may choose either Use Setting in Options, or Use Setting in User Access Rights.
For example, if Post To G/L is controlled by Use Setting in Options, the system will use the setting as defined in Options > Invoicing > Document Control 2
