# Projection administration

## Projection updates 

Projections may change during

* version upgrade (from version 21 -> 22) delivered by IFS,
* service update (SU) delivered by IFS twice a year, 
* patching provided by IFS between SUs,
* customized standard projections and custom projections updated during delivery updates 
* custom projections updates via Application Configuration Packages.

If in/out parameters are changed, each flow steps that using updated projection must be manually checked and refreshed.

## How do we know when projection is updated in IFS?

Depending on type of installation (SU, delivery update) different documents are produced. Below are examples of some documents produced.

### Service update

IFS can/should provide high level list of fixed issues to supplier.

### Delivery Notes

Each installation will produce more specific list of changed projections.&#x20;

## Documenting used projections in flow

{% hint style="info" %}
For the time being, before and if we have some other means of mining Projections used in flows, it could be a good idea to add an Annotation to each flow which lists the used projections.&#x20;
{% endhint %}

{% hint style="info" %}
Listing projections used in flows is also needed to grant projections to users in IFS&#x20;
{% endhint %}

## Locating used projection and operations in flow

Use Find functionality in Flow to identify:&#x20;

* Projection
* Operations
